LSU's practice theme on on Tuesday was "competition" and the Tigers flashed a couple of different things.

Here are some notes from the Tuesday session:

1. Injury update

Tailback Leonard Fournette was not on the field and the running back continues to nurse an ankle injury.

Defensive tackle Frank Herron was sporting a yellow non-contact jersey, but did actually take some contact on a offensive line vs. defensive line drill and looked okay.

Starting right tackle Toby Weathersby continues to be out with a foot injury, and defensive back Savion Smith was wearing a yellow non-contact jersey and struggled in a passing drill. Tight end Foster Moreau also was not present after missing Monday's practice. Moreau appeared to suffer an injury toward the end of the win against Missouri Saturday.

2. Offensive line working different combo

After showing some different combinations on Monday, the LSU offensive line was working in two distinct groups Tuesday.

The starting group in practice was: K.J. Malone, LT; Maea Teuhema, LG; Andy Dodd, C; Josh Boutte, RG; Ethan Pocic, RT. Pocic is LSU's regular center, but he was tried on the right side with regular right tackle Toby Weathersby out with a foot injury. Dodd is a junior who has been a backup. Starting left guard William Clapp is out with a arm injury. The No. 2 group was: Chidi Okeke, LT; Garrett Brumfield, LG; Lloyd Cushenberry, C; Donavaugn Campbell, RG; Adrian Magee, RT.

3. Quarterbacks were working on putting air under the ball

In his Monday press conference, LSU head coach Ed Orgeron said he wanted to stretch the field in the passing game, and to do that, the Tigers would have to be successful on the deep shots they took instead of just taking them for show.

In the first two portions of practice, the LSU quarterbacks were specifically working on getting air under the ball to "give the receivers a chance."

The Tigers worked a drill where the quarterbacks started one yard ahead of the goal posts, took a three-step drop and then let the ball go, with the ball having to travel over the goal post. The drill worked on the quarterbacks getting full extension with their arms and delivering high balls on "go" routes.

Something to watch moving forward.

4. Defense looked good against offense

The last portion of practice open to the media saw the LSU receivers and tight ends in one-on-one contests. The offense completed 13-of-29 passes against the defense with a strong finish helping to get them closer to 50 percent.

Wide receiver D.J. Chark made an incredible catch on a back shoulder throw, as did true freshman wide receiver Stephen Sullivan. The back shoulder throw could be something the Tigers are looking to utilize against Florida, which often presses receivers line of scrimmage in man-to-man coverage.

Tight end DeSean Smith showed some nice wiggle on a double move and continues to impress with his receiving skills. If Moreau is forced to miss the game, Smith could see more snaps.
